One of these binder bars will be suitably slotted as designated at F and F, Figs. 4 and 6, while there will be corresponding openings for the threaded shanks G and G of the screws in the hollow interior of the opposite binder bar. The slots will preferably be what are generally termed keyhole slots comprising a substantially elongated slot terminating at b one end in a somewhat enlarged opening, as

til

shown most clearly in Fig. openings in these keyhole slots will be of sufficient size to permit the passage into the interior of the slotted binder bar H of the cylindrical heads 0 of the screws.

In thev other binder bar H opposite the keyhole slots F and F and preferably registering with the extremity ofthe contracted portion of the slot opposite the enlarged por tion, openings will be provided through which the threaded shanks G and G of the screws will freely pass, and metallic screwthreaded blocks E, substantially filling in cross-section the rectangular hollow space on the interior of the metallic bar H, as illustrated in Figs. 2 to 5 inclusive.

The ends of the rectangular binder bars H may be left open so that the threaded blocks or nuts E may be easily introduced and secured in position, thus resulting in a cheap construction of the binder bars H, enabling them to be made largely by stamping operations while the threaded blocks or nuts E may be made on automatic machines.

Opposite the extremities of the openings for the screw heads G and G, openings K and M will be formed through the outer walls of the binder bars H, the opening designated at K being designed to permit the introduction of a suitable tool as a screw driver to co-operate with the 6. The enlarged slotted head 0 of the screw, While the opening designated at M in the opposite bar H will be utilized to permit the, lower end of the screw to pass close to the outer surface of the binder bar H when a very few leaves B are in posi tion in the binder.

To afford the desired range of flexibility in making a hinging connection between the. rigid cover backs A and the binder bars H, I terminate the material or board of the cover backs A a short distance from the wall of the binder bars H leaving a space or gap slightl wider than the thickness of the cover backs to allow proper hinging of the covers to the position of Fig. 2 as designated in Fig. 3 by reference character P the same being of a length approximately equal to the thickness of the cover back. 'A hinging or flexible connection between the cover backs A and the binder bars H, I obtain in the following manner: 7

C and the screw shanks nsszsas By the use of glue or other suitable adhesive, I attach suitable flexible material D, cut of the desired size to cover the metallic binder bars H and to extend over the normal inner faces of the cover backs A for attachment purposes, thus securing flexible hinging connections between the cover backs and the binder bars in a simple and economical man ner. The flexible material used for covering the binder bars and for gluing to the cover backs is preferably a good firm grade of woven canvas or other flexible textile material as designated generally by the reference character D.

The manner in which the canvas is applied will be best understood by reference to Figs. 3 and 5 from which it will be seen that I apply the canvas to the inside faces of both cover backs A beginning about as indicated at the reference character S in Fig. 3 and I cut the canvas so that it will extend and bridge the gap or space P; thence to cover the co-operating inner faces of the metallic binder bars I-I; thence the canvas D will be wrapped and glued around the three remaining sides of the binder bars which are preferably rectangular in cross section as shown and I prefer that the canvas also extend around the co-operating inner surfaces of the binder bars as illustrated in the drawings so that the edges of the canvas opposite the edges S will be glued in direct contact with the opposite meeting faces of the binder bars which will result obviously in two thicknesses of canvas on these opposite inner faces and will result in a secure fastening for the canvas at this edge.

The canvas D will also be preferably extended on diametrically opposite sides to afford flaps designated at T for pasting flat on the outside of the cover backs A. The canvas covering will obviously be cut away as illustrated in the portions over the binder bars to permit the openings, as designated at K and M, for the screws C, G to be accessible and also permit the keyhole slots F, F to be accessible.

From the above description it will be seen that I have provided cover backs and bind-er bars hingedly connected in cooperating pairs that are economical to manufacture, in fact, they may be made so cheaply as to be available for the use of students taking commer-' cial courses in business instruction where ledgers, journals and day books of the loose leaf type are desired to be used, under which conditions it will be seen that not only is an economical binder desirable but the number of loose leaves B that will be used in such binders, particularly for students, use will ordinarily not be very great, although there may be considerable variation which may be compensated for or taken care of by reason of the fact that thethreaded screw shanks G, in cooperation with the threaded nuts IE, will permit of rather a wide range of adjustment, and while I show the threaded screw shanks G and G of a substantially uniform length in all of the views, it will be apparent to those skilled in the art that other pairs of screws of different lengths may be substituted to accommodate the binder to various quantities of leaves and that I have provided an economical and useful construction of flexibly connected cover backs and binder bars that presents a binder of book form that may be conveniently opened to a very fiat position as illustrated particularly in Figs. 1 and 2 where the leaves B will lie relatively flat tries thereon, and whether the binder book be in the open position as shown in Figs. 1 and 2 or in the closed position as shown in Fig. 3, all metallic parts of the binder bars are canvas covered and protected so that the same may be conveniently used upon finished surfaces such as polished furniture without abrading or injuring the same.

The mode of manipulation of my loose-leaf binder will be apparent from the foregoing description when it is understood that the leaves B will be perforated to receive the threaded screw shanks G and G in the usual manner; such perforations as is common in this art may take the form of keyhole slots in which the narrow part of the slots will be of somewhat less width than the diameter of the threaded screw shanks G and G.

In operating my binder, a screw driver or analogous tool will be inserted in the slot in the head portion C of the screws by passing the tool through opening K in the binder bar and by rotating the same it will be seen that the binder bars may be tightened upon the leaves to firmly secure them in position over the range of adjustment provided by the length of the threaded screw shanks G and while the relatively fixed position of the screw-threaded nuts or blocks E in one of the cooperating binder bars H together with the fact that the cylindrical head C of the screw will be contained in the opposite binder bar will prevent objectionable looseness between the parts even during periods of adjustment.

In assembling and disassembling the binder bars H, which it will be seen from the foregoing description, must be made in cooperating pairs, the binder bar H Which receives the threaded nut or block E, as illustrated in the drawings, may have one of the screws inserted and screwed into the block in what is the lower bar H, in Figs. 3, 4 and 5. The upper binder bar H, as shown in Figs. 3 to 5 inclusive, and having the key hole slots as illustrated in Fig. 6 and carrying the flexibly connected or hinged cover back, will be brought into a position so that one of the enlarged openings F or F, as the case may be, of the key hole slots, will register for writing or inscribing en-' with the cylindrical head G, of the inserted screw when: the: head, wi l. be. entered? in the: slot; and slid; to: the narrow: end; of the; slot-.
